Art Deco jewellery is characterised by geometric precision, symmetrical patterns, stylised motifs, and a strong influence from modern industrial design and cubism.

Master jewellers of this era predominantly used platinum for its strength and fine wirework capabilities, combined with old cut diamonds, calibre-cut coloured gemstones such as emeralds, rubies, and sapphires.

Authentic pieces often feature period-specific gemstone cuts like old European cuts or step cuts, hand-carved platinum settings, makers marks, and French assay hallmarks indicative of the 1920s.

Such a ring serves as a striking focal point and can be worn alone as a statement piece or paired with minimalist modern clothing to highlight its historical craftsmanship.

Regular professional inspection of the prong settings is essential to secure the stones, alongside gentle cleaning with warm soapy water, avoiding harsh ultrasonic cleaners which can damage treated or natural inclusions in emeralds.
